5-Benzamido-3-trichloromethyl-1,2,4-thiadiazoles and their use as herbicides, fungicides and insecticides

Abstract

Disclosed are selected 5-benzamido-3-trichloromethyl-1,2,4-thiadiazole compounds of the formula: <IMAGE> wherein R is phenyl which is unsubstituted or substituted by at least one member selected from the group consisting of lower alkyl having 1 to 4 carbon atoms, lower alkoxy having 1 to 4 carbon atoms, nitro and halo. These compounds are shown to have post-emergence herbicidal, fungicidal and insecticidal properties.

What is claimed is: 
     
       1. A compound of the formula: ##STR4## wherein R is phenyl which is unsubstituted or substituted by at least one member selected from the group consisting of lower alkyl having 1 to 4 carbon atoms, lower alkoxy having 1 to 4 carbon atoms, nitro and halo. 
     
     
       2. The compound of claim 1 wherein R is unsubstituted phenyl. 
     
     
       3. The compound of claim 1 wherein R is phenyl substituted by at least one lower alkyl group having 1 to 4 carbon atoms. 
     
     
       4. The compound of claim 1 wherein R is phenyl substituted by at least one lower alkoxy group having 1 to 4 carbon atoms. 
     
     
       5. The compound of claim 1 wherein R is phenyl substituted by at least one nitro group. 
     
     
       6. The compound of claim 1 wherein R is phenyl substituted by at least one halogen atom. 
     
     
       7. The compound of claim 6 wherein said halogen atom is chlorine or fluorine.
